This is a great book - it reminds me of a watered down version of 78 Degrees of Wisdom (by the same author).
It splits the tarot (as most books do) into Major and Minor Arcana and offers the usual explanations, however, one nice touch at the end of each Major Arcana section is a "reading" that you can do for each card, for example, it gives you a 6 card spread to ask how The Fool has influenced you in several ways ("How have I been a Fool in my life" and "What gifts does the Fool bring me" etc). The Author also discusses her system of splitting the Major Arcana into 3 sets of 7 cards - with the Fool at the beginning, showing the archetypal Fools Journey.
The Minor Arcana section has the theme of numbers spreading through it, for example "2" is about "balance" and "decision", 4 has the theme of "structure" and a description follows for each card.
Both the Minor Arcana and Major Arcana sections discuss the symbolism in each card, however, it is not as in-depth as "78 Degrees of Wisdom".
As is the custom these days the Court Cards have their own section and discussion which is good. The final chapter discusses readings and spreads such as a basic 2 card spread up to the celtic cross.
This is a fantastic book for the beginner and more experienced reader. Given the choice I would still chose "78 Degrees of Wisdom" over this book simply because it has more depth to it, however, the conciseness of this book makes it far more accessible to quickly read up a particular section or card.
This is a must for anyone who is interested in Tarot and is highly recommended - if you already have 78 Degrees of Wisdom I still think you will appreciate the concise nature of the book and the good layout as a quick way to get to the basics whilst still referring to 78 Degrees for more depth and discussion.
